How to convert Megameter to Light-year

Conversion factor and calculation steps from Megameter (Mm) to Light-year (ly).

Conversion logic

Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.

1 Mm = 1000000 m

1 ly = 9.46073047e15 m

1 Mm × 1000000 = 1000000 m

1000000 m ÷ 9.46073047e15 = 1.05700083e-10 ly
